2 What is openEHR?  The openEHR Foundation is a non-profit established in 2001 –  Open source specifications for a logical EHR architecture  Based on 18+ years of international implementation experience including Good European Health Record Project  Superset of ISO/CEN EHR standard  Engineering paradigm  Separation of clinical and technical concerns  International Community

3 “Healthcare's Big Problem With Little Data”  Gartner’s hype cycle: “Big Data” heading toward the “Peak of Inflated Expectations”  “In the meantime, however, ”little data” in healthcare continues to give us all peptic ulcers”  “Clinical data at the unit level is chaotic and dysfunctional because it’s not easily transferable or usable outside of the system that first created it. In a world of competing financial interests and an increasingly mobile population – every patient encounter represents an opportunity for technology vendors to lock-in providers.”  “Historically, the crutch that many software vendors have relied on is the format of the data itself.”  problem-with-little-data/ - April 28, problem-with-little-data/

4 Clinical diversity  Variety of data represented  Free-text vs Structured  Normal statements  “Nil significant”, “NAD”  Graphical  Fractal nature of medicine  Different clinicians:  Prefer different approaches  Need different levels of detail  Need to record/exchange information on a per patient basis  MYTH: “One size fits all”  Image – eg homunculus  Multimedia  Diagram, video, ECG wave  Questionnaires, checklists

5 Clinician-driven health data Standardised clinical content definitions ORTHOGONAL APPROACH  Longer-term viewpoint

6 Standardised clinical content definitions Reference Model Clinician-driven health data Computable, standardised clinical data definitions/models

7 Semantic Queries Terminology Mappings/ Subsets Code Skeletons Data Sets UI Forms XML Schemas HTML Display Messages Clinician-driven EHRs Standardised clinical content definitions Computable, standardised clinical data definitions/models Decision- Support Reference Model

8 ArchetypesTemplates openEHR artefact ecosystem Semantic Queries Terminology Mappings/ Subsets Code Skeletons Data Sets UI Forms XML Schemas HTML Display Messages openEHR Clinical content models Decision- Support Acknowledgements: Hugh Leslie, Thomas Beale openEHR Reference Model

9 Archetypes & Templates  Are ‘agents for change’  Require a change of mindset  Require upfront planning & coordination  Not more time  Remember re-use+++  REQUIRE CLINICIAN LEADERSHIP & ENGAGEMENT  Ensure quality of clinical data  Warrant data is safe & ‘fit for purpose’  Fulfils quality remit for professional clinical colleges

10 openEHR knowledge artefacts ArchetypeTemplate  Foundation building blocks  = Structured, computable specification for one single clinical concept  Maximal data set  Universal use-case  Design once, high re-use  10 to save a life; max

11 Archetypes openEHR two level modelling Archetypes Templates Archetypes CLINICAL TECHNICAL Software is built independently of the content

16 ‘The openEHR Methodology’  Clinician-driven:  Requirements gathering  Model development  Archetypes  Templates  (Terminology RefSets)  Model verification  Governance  Publication  Endorsement/Approval  Maintenance  Distribution Clinician Engagement

17 Typical EHR methodology Requirements gathering User Interface/ Workflow tweaking Software Development Clinicians + Informaticians 0 Engineers ++ Clinicians 0 Informaticians 0 Engineers ++ Clinicians + Informaticians 0 Engineers ++ Clinicians allowed to participate

18 Typical openEHR methodology Clinicians ++, Informaticians ++, Engineers + User Interface/ Workflow tweaking Software Development Clinicians 0, Informaticians +, Engineers ++ Clinicians ++, Informaticians ++, Engineers + Requirements gathering Model Development & Verification Clinicians actively participating

19 Traditional Requirements gathering  Identify:  Documents/Forms  Existing systems  Etc  Direct Clinician Engagement not easy  Usually a Clinician Interrogation -> Engineer Interpretation process  Success depends on the ‘right’ questions being asked by engineers  High risk of misunderstandings  No method for Clinician confirmation/validation

20 openEHR Requirements gathering  No rocket science:  Documents/Forms  Existing systems  Etc  Direct Clinician Engagement:  Health Informatician-led  Re-use existing clinician-verified models as starting point  Can develop templates in real time  Clinician buy-in  Minimise F2F meetings – $$$/opportunity cost

21 Specification Development 1. Archetypes  Development/Re-use  Asynchronous, online reviews  clinician verification 2. Terminology RefSets  Development/Re-use  Asynchronous, online reviews  clinician verification 3.Templates  Development  Asynchronous, online reviews  clinician verification Software Engineers

22 2 Practical Approaches RMP On-call – Initial F2F, then virtual Hearing Health – 90 % virtual  2 day F2F Workshop  Identify requirements  Data  Workflow  ‘Live’ Documentation  Mindmap  Template development  Reuse existing Archetypes  Constrain for use-case  Return home 1. Archetypes  Build new  Clinical Review 2. Update Templates with new Archetypes  Clinical Review  Identify existing forms/specifications  Mindmap concepts and ‘documents’  Developed by informaticians/clinical expert  Archetypes  Build  Clinical Review  Templates  Build  Clinical Review

23 Hearing Health Reqts – Phase 2

24 Hearing Health Reqts – Phase 1 Estimate: 85% re-use

27 Archetype Review

28 Template Display/Review

29 RMP On Call  Remote doctors in Darwin/Alice Springs supporting ‘on the ground’ clinicians  Manage major events in the remote communities  Need retrieval by RFDS/Careflight?  Complex process that varies depending on:  Who is available locally  The risk to the person and professionals  The means of transport available  The make up of the evacuation team

30 RMP Requirements 2 Day Workshop -> multiple mind maps as ‘live’ evolving documentation of requirements Identify Templates required Identify Concepts/ Archetypes required

31 RMP Workflow

32 RMP live Workshop Template  Template created during the workshop in parallel with the mind map  Clinician engagement +++  Technical specifications created:  Driven by direct clinician input and validation when re-using existing archetypes  Identify gaps. Resolve by:  modification of existing archetypes, OR  Creation of new archetype

33 CKM template for Clinician review 3 Templates Produced:  RMP Assessment  Clinical Summary  Referral

34 RMP On-call Archetype Re-use Re-use of existing1650% re-used, no changes 59% re-use Modify existing – minor29% re-used with some enhancements from newly identified requirements Modify existing – major1 New development13 41% new

35 Northern Territory Re-use  14 unique templates  1 Antenatal  10 Hearing Health  3 RMP on-call  400 instances of 81 unique archetypes  Number of archetypes per template: 2…58  Number of times an archetype is used across all templates: 1…33

36 IT’S. ALL. ABOUT. THE. DATA.  Change the viewpoint  Data (UHR) vs Application or Message  Break down silos - App/Tech/Vendor independent  Active health information sharing  Life-long cohesive health record  Change the approach  Clinician-driven+++  Express clinical variability via templates, based on tightly governed archetypes  Sustainable Re-use

37 THANKYOU   International CKM –  Australian CKM -  UK CKM -  Brazil  ?Slovenia  ?Norway
